SPECIFICATION forming part of Letters Patent No. 492,828, dated March 7,1893.

Application filed April 23, 1892.

' citizen of theUnited States of America, residing at Bloomington, inthe county of Monroe and State of Indiana, have invented certain new anduseful Improvements in Lamp-Fillers, of which the following is aspecification, reference being bad therein to the accompanying drawingand the letters of reference thereon, forming a part of thisspecification, in which The figure of the drawing is a side view ofalamp bowl havingaportion broken away to more clearly show the fillingtube located within. v

This invention relates to certain improvements in lamps and moreparticularly to the device for filling the lamp, and for indicating theheight or quantity of oil within the lamp, which improvements are fullyset forth and explained in the following specification and claim.

Referring to the drawing A represents the bowl of an ordinary lamp, andB represents the feed aperture consisting ofa tube extending from thebreast of the bowl down for some little distance toward the bottorn,itbeing intended to have it extend to at least about half way down towardthe bottom from the upper part or breast of the bowl. The prin- SerialNo. 430,424. (No model.)

cipal new feature is that the inner walls of the tube B are polished soas to reflect like a mirror, so that when oil is poured in at this tube,the amount or height of the oil can be easily seen by reason of thereflection of the polished inner wall of the tube, and thus prevent anoverflow of oil when filling the lamp.

If the tube B were not polished or bright on its inner side like amirror there would be no reflection and the tube would not operate toindicate the height or quantityof oil in the lamp, and without greatcare an overflow would result in filling the lamp.

There should be a vent hole to permit air to escape when the lamp isbeing filled, but

generally enough will escape around the Wick for that purpose.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit:

The combination of the lamp bowl A. and the combined filling and sighttube B having its interior surface polished so as to reflect thematerial within said tube substantially as and for the purpose setforth.
